Plymouth works correctly, but it shows after I log into lightdm (so I have to push ctrl+alt+F7 to show the desktop again). Why do you think it loads after I login? It is a known issue? Thank you.
I followed the steps of the wiki to enable plymouth:
HOOKS=(base udev plymouth ... plymouth-encrypt) # since i installed manjaro with full disk encryptation.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash cryptdevice=UUID=5155c252-cbb2-40f6-99cb-2390809ce5c3:luks-5155c252-cbb2-40f6-99cb-2390809ce5c3 root=/dev/mapper/luks-5155c252-cbb2-40f6-99cb-2390809ce5c3 apparmor=1 security=apparmor udev.log_priority=3
Then I regenerate instrams with:
sudo mkinitcpio -P && sudo grub-mkconfig -o /boot/grub/grub.cfg && sudo update-grub
When I reboot I see 'quiet' working, but 'splash' shows after I log into lightdm.
